The Puffin is an American proposed hover-capable, electric-powered, low-noise, personal vertical takeoff and landing (VTOL) technology-concept proprotor aircraft. The concept design was projected to be capable of flying a single person at a speed of 150 miles per hour (241 km/h), with range expected to be less than 50 miles (80 km) with 2010-vintage Lithium-iron-phosphate battery technology. The design specified a 13.5 foot (4.1 m) wingspan, standing 12 feet (3.65 m) tall on the ground in its take-off or landing configuration.
